Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 235,126,745, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 235,126,745 | |
| -1 | -235,126,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 235,126,745.
Example:
1 x 235,126,745 = 235,126,745
and
-1 x -235,126,745 = 235,126,745
Notice both answers equal 235,126,745
With that explanation out of the way, let's continue. Next, we take the number 235,126,745 and divide it by 2:
235,126,745 ÷ 2 = 117,563,372.5
If the quotient is a whole number, then 2 and 117,563,372.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 235,126,745 | |
| -1 | -235,126,745 |
Now, we try dividing 235,126,745 by 3:
235,126,745 ÷ 3 = 78,375,581.6667
If the quotient is a whole number, then 3 and 78,375,581.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 235,126,745 | |
| -1 | -235,126,745 |
Let's try dividing by 4:
235,126,745 ÷ 4 = 58,781,686.25
If the quotient is a whole number, then 4 and 58,781,686.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 235,126,745 | |
| -1 | 235,126,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 49 | 85 | 119 | 245 | 595 | 833 | 4,165 | 56,453 | 282,265 | 395,171 | 959,701 | 1,975,855 | 2,766,197 | 4,798,505 | 6,717,907 | 13,830,985 | 33,589,535 | 47,025,349 | 235,126,745 |
| -1 | -5 | -7 | -17 | -35 | -49 | -85 | -119 | -245 | -595 | -833 | -4,165 | -56,453 | -282,265 | -395,171 | -959,701 | -1,975,855 | -2,766,197 | -4,798,505 | -6,717,907 | -13,830,985 | -33,589,535 | -47,025,349 | -235,126,745 |
